RODENT AND INSECT EXTERMNATOR.

Application filed May 17, 1927. Serial No. 191,992.

`This invention relates to improvements made of steel 10, having one of its ends in devices for exterminating rodents, insects closed by a cap 12, the extreme outer end of or the like by means ot' agas adapted to be which is formed into a nipple 11, and which forced into the hiding places or abodes o't is adapted to be screwed upon the end oi the these animals, and it is the principal object cylinder 10, as indicated. This end ot the 60 oli' my invention to provide a gas generating cylinder is closed by a circular plate 13 havand distributing gun adapted to receive and ing a plurality oi openings 14:, anda gas exchangeably hold cartridges iilled with a collecting, periorated hood 15.

After setting up the gun by means of the frame 38 in 'front of a mole hole or the like, the plunger is driven home by ihitting the yknob 23 driving the needle into .thecartridgeand exploding gas which is then expelled .through openings 36'and lll and Vthe nipple illand forced into lthe holes of risino a Steel c .linder .a cartridge holderV removably vheld therein, a V1handle, and a means guided by said yhandle vto be driven into :said cylinder for exploding vthe gas developing 4cartridge -in said holder, means for allowing the exhaust of `the gas developed fromsaid exterminator into-the abodes Voli' Ltheanimals, anda means forsupporting the `exterminator in action.
